Well I was pretty sure from the beginning that Eddie and Jase were a couple and also that Luke was gay too. And that Aaron is Luke's ex-boyfriend. Luke just couldn't tell Rory about Luke being his ex until everything was out about Eddie and Jase. None of the 3 Eddie, Jase, and Luke knew how Rory would react to any or all of them being gay. They didn't want to push him farther away than he already wanted to be from the beginning. I don't think it will go over to the 3 of them that Aaron has outed them to Rory.
